IMPROVEMENT IN MACHINES FOR TURNING AXLES.

The Schedule referred to ln these Letters Patent and making parl: of the same.

I, ARTHUR F. MOORE, of Florence, in thecouuty of Switzerland and State of Indiana, have invented certain Improvements in Machines for Turning Spindles of Wooden Axles, of which the following is a specification.

Nature and Objects.

invention consists in the employment of avstationary frame furnished with a center at one end, and an adjusting-frame, provided with set screws, at the other, for the purpose of properly centering and adjusting the spindle-blank to be operated upon, and a carrier-bar, provided with a lead-screw and traversing cutter-head, by means of which the spindle is cut' to the proper conical or cylindrical form, as may be desired.

Description of Drawing.

Figure l is a side view of the complete machine;

Figure 2 is a rear end view of the same;

Figure 3 is a sectional view; and

Figure 4 is a front view of the cutter-head.

General Description Let A represent the main frame of the machine, which may be of the form shown, or its equivalent;

B, a finished axle spindle, shown, for purposes of illustration, as secured in the frame while being turned 5 and G, an adjusting-frame, secured rigidly to the mainframe, (see figs. 1 and 2,) and provided with set-screws, au, at top and bottom, for adjusting'the position of the axle and fixing it'rmly in place.

lA. hollow cylinder, D,'is secured to or forms a part of the main frame A,and projects from the turnedup portion, Where it is attached, ina direction parallel with the bottom of the frame.

On the innerend of this cylinder is rigidly secured a toothed wheel, I1.

Through the cylinder D and wheel b, which form a long bearing therefor, extends a spindle, to the front end of which is rigidly secured the cross-handle H, and to the rear or inner end the transverse bar E.

Beyondthe rear face of this bar the spindle is prolonged', to fornia dead-center, i, the intermediate space being threaded for the reception of a milled steady-nut, L

The transverse bar E is placed exactly at right angles to the spindle to which it is attached, and carries a toothed wheel, c, equahin'size to the wheel l), and meshingtherewith.

The'l'a'rge journal of the wheel c is mortised, (see g. 3,) for the reception of the square k on the end of the lead-screw T, to which it imparts motion.

The lead-screw has a bearing at its outer extremity n, in a lip secured to a carrier-bar, F.

The form of this bar is better shown in the drawing, vfig. l, than can he described.

The longitudinal portion, which'carries the cutterhead G and the lead-screw T, is straight and true.

At the point h' it is mortised to receive an L-shaped tenon on one extremityrof the bar E, to which it is t hinged by the pin h. l The transverse portion is enlarged at vthe point where the cylinder D passes through, the opening for its passage being oblong or elliptical, and somewhat larger than the said cylinder.v

vThe end of' the said transverse portion of the bar F is formed so as to overhang or in close on two sides. one extremity oi the bar E, upon opposite sides of' which two set-screws, e e. have a bearing. The object of these will be shown further on.

The cutter-head G (see figs. l and 4) is mortised longitudinally for the reception of the bar F and square nut s on the lead-screw, andhas a vertical socket, as shown, for the reception of the shank of the cutter N.

The set-screw Xis to secure the cutter in its place. The uses of the screws y and z will be explained in the Operation' of the Machine.

The axle-blank is lined-np1 and placed in the frame so that the axis of the spindle will be parallel with the bottom of the main frame.

Theiine line indicates the position of the axisv 'in the drawing.

' The set-screws c c-are screwed down firmly, and the steady-nut S run up until it bites well into the wood.

The carrier-bar Eis now set precisely parallel with the under side ofthe spindle-blank, or, in other words, at such an angle with the axis of said blank as\ will give the proper conical form. This adjustment is accompiished by means of the set-screws e c.

The cutter N is now set in the proper position to cut a spindle of the desired size, and the machineV is ready. 'The operatorV turns the handle H inprecisely the same manner as that of an anger, which causes the carrier-bar to rotate around theA spindle as a center, and the cutter to generate a cone of the proper size by cutting away the superluous wood of the blank.

It is fed along by the feed-screw T until the desired length of spindle is cut, when the setscrew y is loosened and a tightened, which causes the cutter to rotate without advancing, thus cutting the proper shoulder.

I especially disclaim any such parts of my machine parts appertainng thereto, when the same are conas may conflict with the patent of John Burt, dated sti-noted, arranged, and combnedin the mannershown, August 4, 1868, and numbered. 86,594, for a device and for lshe purposes set forth. similar to mine. i Witness my hand. this 26th day of January, 1871.

itaving thus described my invention, ARTHUR F. MOORE.

c aim- The main frame A, adjustingrame G, cylinder D, transverse bar E, carrier-bar F, handle'and spindle H, nut S, lead-screw T, cutter-head Gr, and all the minor Witnesses:
